IMPROVEMENT IN BREAST-STRAP HOOKS.

Specification forming part of Letters Patent No. 218,923, dated August 26, 1879 application filed May 26, 1879.

To all 'whom it may concern:

Be it known that I, CHARLES B. BRISTOL, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Breast-Strap Hooks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Fignre l, perspective view; Fig. 2, section through roll.

This invention relates to an improvement in devices for connecting the breaststrap to the pole, its object being principally to avoid the use of the metal breast-strap Aslide commonly used, and the invention consists in the construction Vhereinafter described, and particularly recited in the claim.

A represents a hook provided with a springtongue, B,substantially as in snap-hooks. On the shank ofthe hook an open frame or loop is formed, consisting of the two ends C D and two sides, E E. Across this loop, from side to side, is a spindle, F, on which is placed a wood roll, H, loose, and so as to revolve freely.

The breast-strap is passed between the roll H and the end C, and so that the hook may be engaged with the pole and the strap take its bearing on the roll H, and, because of the anti-frictional character of the roll, no slide is required on the strap.

The end D holds firmly the two sides of the loop, and serves as a safety-guard, for should the strain upon the roll be so great as to break it, the end D would catch the strap.

The particular kind of snap-hook to be employed is immaterial, it only being essential that it shall be a snap-hook, and made substantially a part of the frame C D E, and that the roll H shall be Within the frame between the two ends. This device makes a much stronger and more convenient arrangement than the usual slide and ring, as well as more desirable.

I do not broadly claim a snap-hook connec- CEAS. B. BRISTOL.
